Gas Plant / Dictamnus albus 'Purpureus'


This photo was taken on 24 June 2015, when I called in at the Reader Rock Garden after a volunteer shift. I had taken photos of this plant before, but I don't remember reading up about it. I can now see why it is called Gas Plant - quite fascinating.
"Dictamnus is a genus of flowering plant in the family Rutaceae, with a single species, Dictamnus albus, which has several geographical variants. It is also known as burning bush, dittany, gas plant, and fraxinella. It is an herbaceous perennial, native to warm, open woodland habitats in southern Europe, north Africa and much of Asia.
This plant grows about 40 cm (16 in) to 100 cm (39 in) high. Its flowers form a loose pyramidal spike and vary in colour from pale purple to white. The flowers are five-petalled with long projecting stamens. The leaves resemble those of an ash tree.
In the summer months, the whole plant is covered with a kind of flammable substance, which is gluey to the touch, and has a very fragrant, lemony aroma; but if it takes fire, it goes off with a flash all over the plant. The name "burning bush" derives from the volatile oils produced by the plant, which can catch fire readily in hot weather, leading to comparisons with the burning bush of the Bible, including the suggestion that this is the plant involved there. The daughter of Swedish botanist Carl Linnaeus is said to have ignited the air once, at the end of a particularly hot, windless summer day, above Dictamnus plants, using a simple matchstick. The volatile oils have a reputed component of isoprene." From Wikipedia.
